Security researcher Yuhang Wu at depthfirst has published a working proof-of-concept (PoC) exploit that executes commands as git on an unpatched self-managed GitLab 18.11.3 server. An ordinary authenticated user triggers it by committing two crafted Jupyter notebooks and requesting their diff. The chain needs no administrator rights, continuous integration (CI) runner access, victim interaction

The North Korean threat actors behind the ClickFix-style campaigns that employ typosquatted Zoom and Microsoft Teams domains have been found to operate an active phishing kit to impersonate the videoconferencing platforms in social engineering campaigns designed to deliver malware. "BlueNoroff has operationalised trust abuse by combining compromised industry contacts, social engineering, wallet

Researchers H0j3n and Aniq Fakhrul published a working exploit on July 24 that lets a low-privileged Active Directory user obtain a certificate for a Domain Controller and authenticate as that machine. They codenamed the flaw Certighost. Because Domain Controller accounts carry directory replication rights, the resulting Kerberos credential can retrieve the krbtgt secret through DCSync.

Cybersecurity researchers have disclosed a critical vulnerability in OpenAI's ChatGPT Workspace Agents that could have allowed a single phishing link to stealthily build, authorize, and deploy an autonomous artificial intelligence (AI) agent inside a victim's organization. The vulnerability has been codenamed AgentForger by Zenity Labs. The issue has since been addressed by OpenAI as of June 8,

A crafted SVG submitted to Bing's image search ran commands as NT AUTHORITY\SYSTEM on Microsoft's production image-processing workers, and as root on the Linux machines in the same fleet. XBOW's testing got the same result on workers across different hosts and network ranges, so the problem sat in Bing's image tier, not on one bad machine. Microsoft issued two critical CVEs, CVE-2026-32194 and
